One minute review
The Metaspeed Sky+ sees Asics update the original Metaspeed Sky, a shoe that has arguably put it firmly in the conversation of carbon-plate super shoes, alongside the peak performance of Nike and Adidas.
With the Sky+, Asics promises improvements in many departments, including an improved upper, more foam in the midsole and a repositioned carbon fiber plate to make this an even better shoe for running fast over all distances.
It still feels to us like a shoe that really comes into its own for half to marathon distances, and it’s one of the best running shoes for this. However, many will also be able to use it to chase PBs at shorter distances.
The changes to the upper don’t feel huge, but the extra foam in the midsole should make it a much better partner for running the marathon distance compared to the first Sky.
It’s still very expensive and there are definitely still questions about durability, especially on the back of the shoe. If you’ve got the running style to match the qualities the Sky+ offers, here’s a shoe that rivals the best Nike and Adidas have to offer for those already running super fast 5K, 10, half marathon and full marathon times and want to feel like they can go even faster.
The Asics Metaspeed Sky+ was launched in June 2023 and costs £225 in the UK (opens in new tab)$250 in the US (opens in new tab) and $330 in Australia (opens in new tab) from the Asics store in your area.
Design Verdict: 4/5
Like its predecessor, the Metaspeed Sky+ is a shoe designed to keep weight down and provide a design that can best help you when it comes time to race.
Along with the Metaspeed Edge+, the Sky+ is the option in Asics’ new performance shoe duo aimed at what it calls ‘stride’ runners. These are runners who increase their stride length as they increase their speed, but do not or only slightly increase the number of steps they take per minute.
The Sky+’s brother, the Edge+, is for ‘cadence’ runners who also increase their speed by increasing stride length, but also increase the number of steps they take per minute.
With the Sky+ you get a shoe that weighs 205 grams, which is 5 grams lighter than the first Sky, despite the addition of more midsole foam. There’s now 4% more of the same FF Blast Turbo midsole, still made from a nylon-based foam that’s built to be lightweight and provide a responsive shoe to run in. It retains the same 5mm heel-to-drop with a 34mm stack at the heel and 29mm at the forefoot.
The carbon fiber plate is also still there, although it has been moved to now sit much higher in the midsole and with the same curved sole design is intended to improve the energy return credentials of the Sky+.
In the upper department, Asics has made some changes to what it calls a Motion Wrap upper, which is still made of mesh, but changes have been made to what feels like lighter braided laces and offers more structure than the first Sky. The tongue is thin, the room in the toe box felt just right and the fit at the midfoot and heel felt good for us in our UK size 8.
Last and by no means is that outsole, which uses Asics’ AsicsGrip outsole rubber to deliver something that offers strong traction on roads. There’s still more of that rubber out front compared to further back, so putting most of that power in the forefoot should reap the benefits of the satisfyingly grippy outsole.
Performance rating: 4/5
Like the Sky, the Sky+ is designed as a shoe that you slip on when you want to feel your fastest. Whether it’s race day or training at your race pace, this is where you get the most out of what this shoe has to offer. Whether that’s the custom carbon plate, an extra helping of light, or FF Blast Turbo midsole foam wrapped in that thin mesh upper.
We wanted to test it in those conditions, run it for fast 10k runs, put it to the test in a 5K time trial with Asics and race it in the Edinburgh Half Marathon. We also wore it for two long training runs to see how it reacts when you want to go further. Knowing the distance you want to run is essential in finding the right running shoe for you.
Some like the Sky at shorter distances, but we couldn’t quite handle it on our spirited 5k and 10k race distances. We had a much more enjoyable experience racing and training at marathon and half marathon pace. That’s where this shoe really feels like it comes into its own. That midsole foam feels soft and springy and now there’s more of it, making it better suited for long-distance rides when you want that extra level of support and comfort.
It’s a shoe that makes you feel you can run effortlessly at a fast pace and sustain it for a distance without feeling particularly tiring on the legs or difficult to put in, which is what makes this shoe so special. Asics made some significant changes here with the repositioning of the carbon fiber plate to promote better energy return and add more of that midsole foam, although we can’t say they drastically changed our experience running in this shoe compared to his predecessor.
The grip on the outsole is the perfect fit for road running, but as with the Sky there isn’t much protection further back in the heel compared to the forefoot. If someone hits that heel, that meant that after about 70km of running in it, there was some wear and tear on the heel of one side of the shoes.
It was the same story on the original Sky and certainly leaves question marks over the durability and regularity with which you should use this shoe. We say save it for when it really matters.
Overall, however, this is a super shoe that can be called in the same sense as Nike’s Alphafly and Vaporfly shoes and Adidas’ Adizero Adios Pro shoes. It’s built for speed and while it will burn a huge hole in your pocket, the quick rewards are there if you decide to part with your money.
